Grinder Sewage Pumps

 For Grinder Sewage and wastewater applications, with more than 30 years experience in manufacturing sewage grinder pumps, including sump pumps, effluent pumps, water pumps and mag drive fountain pumps. We have a wide range of sizes available.

We have discontinued the sale of our entire "Sewage, Grinder, Sump" line of products!

Please visit our floating fountain page for our current pump offerings.

Important tips to consider when sizing your pump - The Length of the horizontal pipe is also an important factor when choosing a grinder sewage pump. Every 10’ of pipe equals the same restrictions as 1’ of lift. The shut off means that is the maximum height that the grinder sewage pump will lift. So you will get "0" flow at the shut off height.


Grinder Sewage Pump

A Grinder pump is a centrifugal pump, which is equipped with a cutting system to facilitate grinding/maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are macerated by the grinder system. A sewage or septic grinder pump, (there is more than one grinding method) reduces sewage to a finely ground slurry of waste and water,  which the pump can then force the slurry to its destination. Due to its unique solids handling capabilities, the grinder pump is often used for pumping sewage, sludge, manure, and other liquids that contain large or tough solids. Whether you're replacing an existing grinder pump or need a pump for your new sewage system, we have several options for any number of tank sizes.

What does a Grinder Pump do?

A sewage grinder pump macerates sewage so that it can be pumped through a (usually smaller-diameter, perhaps 2") force main to an uphill septic tank or sewage pumping station or to a municipal sewer line, all of which are in this case located higher than the pumping location. Where a lot of vertical lift is needed ( head pressure), a submersible sewage grinder or effluent pump will be used and will be installed at or near the bottom of the holding tank. Though we can't see the pumps in this photo - they are below the sewage level in this pumping chamber - that's what we'd expect to find installed in this municipal sewage lift station.

Many subdivisions were located outside of existing municipal sewage pump systems. Often, the most desirable lots presented physical constraints on traditional septic or sewage handling systems. Some of these constraints were: waterfront locations, hilly terrain, high water tables, and extreme cold weather areas. Other possible constraints were: areas where soil conditions resulted in septic system bans or gravity sewers could not be physically, or economically, reached. Those constraints resulted in new demands for alternative home sewage systems. Those demands resulted in the development of pressurized sewer systems to handle wastewater for communities, single residences or in light commercial applications. Many of these pressure pump systems were serviced with grinder pumps.

Grinder Pumps are used to pressurize small diameter plastic lines in areas where large gravity lines are impractical or uneconomical. Discharge points may be existing gravity sewer mains, large pump lift stations or direct to central treatment systems. All that’s needed in this type of system is a grinder pump or pumps, a pump station to collect residential sewage, a control panel to turn the pump on and off, some small diameter plastic pipe and a small trencher. Grinder pumps can actually reduce infrastructure costs. Since these pumps cut large solids into smaller particles and pump at higher pressures, residential sewage can be pumped through smaller diameter pipes to greater elevations and longer distances.
